To all whom. it may concern:

Be it known that I, RICHARD W. HAMANN, United States, and resident new and useful Improvements in Boiler- Flue Cleaners, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, formlng a part hereof.

My invention relates to boiler flue cleaner, or a device utilized for directing jets ofsteam or compressed air against the ends of boiler ilues for the pur Ose of removing all accumulation in saidlues and blowing the same through s'aid tubes and into the forward portion of theboiler, from whencesaid accumuin the lengths `and arrangement of parts,

lation passes into the stack.

The principal object of my invention is to construct a'boiler lue cleaner which is particularly adapted for use in connection with marine boilers, although with slight changes of connecting ipe, and the like, said flue cleaner can be a vantageously em loyed in connection with any form of bo` er in which fines are utilized.'

A further object of my invention is to provide a perforated head through which the steam or compressed air is discharged, and which head is arranged for vertical movement immediately to the rear of the tube area of a boiler.

To the above pur oses, my invention cons1sts 1n certain nove features of construction which will be hereinafter more fully set forth, pointed out in the claims, and "illustrated 1n the accompanying drawings, in which:

1gure 1 is a vertical section taken through the rear portion of a boiler and its setting and showmg my improved apparatus located rear Wall in position for use; Fig. 2 is an enlarged horizontal section taken on the line 2*2 of Fig. 1 Fig. 3 is a front elevation of the perforated head from which the steam or compressed air discharges; Fig. 4 is an enlarged vertical section taken through the center of the cleaner, and the housing in which the same operates and Fig. 5 is a horizontal section taken onthe line 5*.5 of Fig. 4.

Referring by numerals to the accompanying drawings: 1 designates the boiler, 2 the i'lues therein, and 3 the rear wall of the boiler setting, which in marine boiler construction is located immediately against the inner face of a vertically disposed sheet .metal wall or plate 4. The housing 5 of sheet metal or analogous material is located in the wall 3 immediately opposite the tube area on the rear end of the boiler, and tted onto the plate 4 immediately to the rear of this housing 5 is an extension housin 6, made in meeting halves and rigidly he d together in any suitable manner. Passing transversely through this extension housing 6 and journaled for rotation in the side walls thereof, is aA horizontally disposed pipe 7, one end of which is closed by a cap 8, and the opposite end being journaled in a union 9, to which is connected a steam or compressed air su ply pipe 10. Fixed on the pipe 7, outside tlife ousing 6, is one end of a lever 11, whichl provides means for rocking the pipe 7 whenthe cleaner is in use, and arranged on this lever 11 is a weight 12, which counterbalances the weight of the nozzle of the cleaner.

Fixed tothe pipe 7 within the housin 6 is a short pipe 13, to which is connected a tubular extension 14, which is formed on or fixed to the hollow head forming the nozzle of the cleaner. This nozzle is In the form of a hollow cylinder 15, closed at both ends, and formed integral with the front side of said cylinder is a rib 16, through which is formed a series of discharge apertures 17, and the apertures adjacent the ends of the nozzle are so inclined as that the jets of steam or compressed air issuing therethrough will diverge so as to spread over the entire tube area on the end of the boiler.

When the apparatus is properly installed, the nozzle or cylinder head 15 occupies a horizontal osition, and when not in use rises immediately in front of the lower end of the housing 5, as shown by dotted lines in Fig. 1.

When it is desir`ed to use theapparatus to clean theboiler flues, the vsteam `or compressed air is drawn on through. the su ply pipe 11, and said steam or compresser air 100 passes from thence through the pipes 7 and 13, through the tubular extenslon 14 into the hollow head or nozzle 15, and discharges from thence through the apertures 17. The

operator now engages the outer end of the 105 lever 11 and moves the same up and down, thereby rocking the pipe 7 and consequently moving the hollow head or lever 15 vertically in front of the housing 5. The j ets of steam or compressed air issuing from the apertures 1B horizon'tzl-lly disposed hollow head connected i7 are those discharged into the rear ends of the boiler' flues, and the force of said jets of steam or compressed air blows all of the soot and like accumulation through said llues and into the forward end ofthe boiler setting, from whence said soot and accumulation passes into the stack. The weight 12 counterbalances the weight of the nozzle or hol? low head 15 while the apparatus is in\ use, thereby rendering the operation ot said apparatus comparatively easy.

An apparatus of my improved construction is simple, inexpensive, is easily operated, and can be advantageously employed in all forms of boilers where lues are made use of.

I claim:-

l.. The combination with a boiler and its setting, of a Huid pressure supply pipe arranged to rock adjacent the rear wall of the boiler setting, a branch pipe leading from the supply pipe through the rear wall of the boiler setting, a horizontally disposed head carried by the forward end of the branch pipe, and there being a horizontally disposed row vof perforations formed through the front wall of the head.

2. The combination with a boiler and its setting, ot' a housing arranged in the rear wall of the boiler setting, -a 'fluid pressure )ipe arranged to rock in the housing, a branch pipe'leading from 'the supply pipe through the houspig, a horizontally disposed head artangjged on the lforward end lol the branch ijiipe, and there beinga horizi'intally disposed iow of' perforations formed throiugh" the frontwall of said head.

3. ln a i :apparatus of the class described, E alluidl l, ,ure supply pipe, arranged to rock adjacent ,thf'e rear wall ot a. tubular setting; a

with `sairllfsiripply pipe, a rib formed. integral withthe front side ol' said hollowhead, and there being a plurality ol discharge apertures fornied through said rib.

Il. iln an apparatus ot' the class described, a housing adapted to be positioned in the rear portion of a boiler setting, a fluid pressure supply pipe arranged to rock in said housing, a horizontally disposed hollow head connected uith the supply pipe, and there being a horizoiitally disposed row of discl'iarge apertures l'ornicd through the iront oi thc hollow head.

5. lu an apparatus ol" thc class described., a. lluid pressure supplyr pipe adapted; to be positioned adjacent the rear end of a boiler, a hollow head connected with said supply l pipe, the front of said hollow head being thicker than the rear portion, and there being a vsingle horizontally disposed row of discharge apertures formed through the front of said head.

(i. The combination with a boiler and its setting, of a housing arranged in the rear wall of the boiler setting, a fluid pressure pipe arranged to rock in the housing, a branch pipe leading from the supply pipe through the housing, a perforated head ar ranged on the forward end of the branch pipe, and a weighted lever connected to the fluid pressure supply pipe, for counterbalancing the weight of the perforated head.

7. y ln an apparatus of the class described, a housing arranged in the rear wall oi' a boiler setting opposite the tube area of the boiler, a tube arranged to suing vertically in said housing, a hollow nozzle carried by the forward end oi' said tube, there being a rib formed integral with the front wall of said nozzle, and there being a single row ofidischarge apertures formed through said rib.

8. .lin an apparatus of the class described, ay horizontally disposed cylindrical nozzle arranged to move vertically adjacent the r ia r end ol a boiler, the front wall of which nozzle is thicker than the rear wall, and there being a single row of discharge apertures loruied through the iront wall oi said nozzle. t). In an apparatus of the class described,
